Just wanted to give an update. Jester made new blueprints so that is what you see now. Thanks go out to Jester so everyone can actually read them!!!!
The measurements are all correct so it should be no problem to duplicate these. I think Jester may have his in by now, but I am not sure. I have driven my truck about 6 miles or so since I had put my transfer case in and I have not had a problem with it. My tires are shot so I don't dare drive it until I have the new rims/tires done. I found out that my transfer case, although it came out of a GMC, was actually a Dodge T-case. so as far as I know, you could use a Chevy or a Dodge T-case for these brackets to work. The advantage of using a Chevy case is that the Yokes from the NP200 will fit on the chevy case so you don't need the conversion U-joints. They are a pain. The dodge case has arguably stronger shafts with 32 spline yokes. The year vehicles to look for are around 1972-1977 Chevy or Dodge.
